Newegg built a DeepZoom catalog built on Silverlight 2.  A power search function was added, so when a customer is browsing they just need to enter a keyword, select “Go” and the results are presented in a much richer way.  The application has a slider bar that adjusts the search results by allowing the customer to drag the bar or each end separately which narrows or widens the search.   The results are updated and displayed as the bar is adjusted.  If the customer wants to look at a product more closely, a deep zoom feature is available which can zoom into the surface details of products in the HD clarity.
